Car dies in gear...

My timing light is at the shop and car is in the drive way so I can't speak to the timing but I did try and twist the dis and it won't move so timing ain't moved. (I don't think)

Carb is holley 4150 750 that been running great for 10 years on the 318 before 2 plug wires hit the header

The 950 was off my 512 CI stroker, I could not get the base gasket for the 750 so I threw the 950 on to get the car home from the shop.

The 750 has all new gaskets and new PV.
